Background

The Spain-Portugal Interconnector Pipeline is included in the first stage of a proposed international project that would continue 162 kilometers across the border to Celorico da Beira, Portugal. The Portuguese section of the pipeline would be known as the Celorico–Spanish Border Pipeline. Both pipelines form part of a larger international pipeline project designed to create a single gas market within the European Union. Some of the gas imported from Spain would also be stored at caverns in the salt dome formations of Carriço, Portugal for potential use in a future emergency.

The European Network of Transmission System Operators for Gas (ENTSOG) refers to the project using the project code "TRA-N-168". Together with "TRA-A-283" (Celorico–Spanish Border Pipeline) it is a part of the "WEST 02" project group which is the first stage of the 3rd Interconnection between Portugal and Spain project.

The European Union's 2021-2030 National Energy and Climate Plan for Portugal states that the Spain-Portugal Interconnector gas pipeline is directly dependent on completion of the South Transit Eastern Pyrenees (STEP) Gas Pipeline between France and Spain. However, the latter project was canceled in early 2019, leaving the future of the Spain-Portugal Interconnector project unclear.

Cancellation

The release of updated project information by ENTSOG in November 2020 included no mention of the project's code "TRA-N-168". ENTSOG's accompanying 'Infrastructure Report' refers to "two cancelled projects" which are investments of REN Gasodutos. The two cancelled projects are the Spain-Portugal Interconnector project and the Cantanhede-Mangualde Gas Pipeline.
